Question
Modify the single-cycle datapath by implementing the ‘load word indexed’ instruction (lwx). Below is the syntax and the encoding. The instruction below reads the word from memory address (t1+t2) and stores it in register t0. lwx $t0, ($t1 + $t2)

a) Explain the functional form of the instruction based on the register names.
b) Explain the functional form based on the instruction fields.
c) Draw the changes on the datapath diagram and highlight them so they're visible
d) Give the values of the control signals.

Explanation / Answer
A)functional form based on register names,we use two registers to do this increment operation.
As feature size reduces, power consumption in the large register file becomes a major concern. I
A registry is a group of keys, subkeys, and values in the registry that has a set of supporting files that contain backups of its data.
B)
An instruction executes changes some register fields then moves over the activation period.
d)A value of x is does not matter if signal is 0 or 1.
